Are these functions supposed to be usable in IFUNC resolvers?
They have the same limitation as
/* Used from outside of glibc to get access to the CPU features
extern const struct cpu_features *__get_cpu_features (void)
Sorry, this does not answer my question.
Shouldn't these identifiers be in the public (non-internal) namespace?
Do we have precedents for such arch specific public functions?
There is modify_ldt.
